Really? That's your experience? Mine is about 180 degrees different. Admittedly, my situation was a pretty unusual one, working for a company that paid the $$$$$ for top-grade support from Rational. But we had Rational engineers (CC and CQ experts, respectively) on site two days a week and always on call. I learned a lot from them (as well as from the on-line resources) about how these products work, and I personally can't praise them enough. Yes, there's some complexity; yes, the products have some quirks and warts; yes, there's a substantial learning curve. In an enterprise environment, you should expect to, and shouldn't be afraid to, climb that curve. The payoff is a suite of powerful, "enterprise grade" tools you can exploit in taming your change management dragons. None of the open source tools I've encountered come close to the depth and breadth of power available in the Rational tools.
